What in the world?! Stumbled upon it while surfing a popular car site recently...

It's a chainlinked (as stated in the video title) 4x4 exhibition of nothing I've ever seen before! The wheels not only work independently of each other, but go a step further to exceed the articulation limits of a otherwise hardcore off-road vehicle. Controlling all of that movement is a Rube Goldberg gear network: 5.38 gears and centrally-mounted ARB air locker, chain gears at the swingarm pivots, and chains inside the swingarms to work Hummer hubs at each wheel.
